,Thisinvention relates to sheet metal covers for sectional boilers such as are employed for domestic heating purposes.

Such aboiler iron sections arranged in parallel relation and section assembly. In the assembly water and steam connection is had between the hollows of the sections, as by means of nipples ar ranged between sections and having threaded or taper fit therewith, whereby seal is had by tightening ofthe bolts, or of the nipples 1f threaded.- Thus when a number of boiler-- section assemblies are completed they may vary cons1derably in long1tud1nald1mens1on due to variations inthe connections between 7 their sections.

" vide for such adjustment in a manner not After assembly of the'sections a heat insulating coating or jacket is applied, which is finished ofi" on the outside by a sheet metal cover. The cover supports thejacket and should, therefore, be a tight fit thereover, and considerable difficulty has been had heretofore in obtaining such a fit.

An object of my invention'is to provide a sheet metal cover for the purpose described which may be adjusted to perfectly fit the jacket of its boiler-section assembly within the limits of assembly variation as described above.

A further object of the invention is to proapparent in the finished boiler after completion of the fit, so that the boiler will present a most pleasing appearance.

The exact nature of the invention together with further objects and advantages thereof,

will be apparent from the following description taken in connection with the accompanying drawings, in which Fig. 1 is a more or less diagrammatic vertical section through a boiler of the class described, completed and with its cover, incorporatingmy invention,

fitted thereover; Fig. 2 is a detail of the cover in section corresponding with that of Fig. l;

. Fig. 3 is a detail in perspective'taken as from the under side of the top plate appearing in Fig. 2 and showing a bolt as secured therewith; and Fig. 4 is an expanded perspective is built up of a number of cast 1929. ,serial No. 563,321.

With reference now to the'd'rawings, 1 is a boiler-section assembly, conventionally shown and comprising a number of hollow sections 2 having connecting portions 3 with nipples 4: interposed therebetween, wherebyintercommunication is had between the hollows of the sections 2, the assembly described being main tained by the bolts 5 extending through suita ble aligned openings in the sections and tightened thereupon as by nuts 6. It will be understood that the boiler assemblyincludes'j theusual firebox formedby aligned openings in the sections 2. 1

The assembly as describedabove mayvary' V in longitudinaldimension so that the nuts 6 may be tightened more or less upon the bolts 5 and the sections 2 on opposite extremities of i the assembly may vary somewhat in distance apart. v After completion of the assembly the same receives a coatingo'r acket'7 of heat insulating materialsuCh as sheet asbestos fiber Whereupon'the whole'is ready to receive a sheet metal cover for finish purposes and to protect and maintain the jacket 7.

According to my invention I form the cover with respect to the showing of Fig. 1, ofthree pieces,- comprising opposite end members 9 arranged transversely of the as sembly and the, top memberll arrangedlongitudinally' ofthe assembly; The end members have'associated therewith as by form'- ing from" a single piece of sheet metal, a'mold' portion 12 extending into the horizontal plane as at 13-. ,The mold portion is preferably bent under and folded back uponitself as at 14 to formfa lip Or bead 'portionpresenting a smo'oth'edge andto stilfenthe associated part s'f Thislip portion'is perforated 17. corresponding with the slots through i j which thebolts pass. The perforations17 of the member 11, however, may be circular. Associated with each perforation 17 is a nut 18. l The nuts 18 are provided with threaded openings 19 and are secured with l the under sideof the top member 11 with their openings 19 aligned each with'its per-" foration 17. To this end nuts 18 are-elongated asshown inFig. 3 eachhaving anend" 20 extending from its opening 19 and sp'o-t welded as at 21 with the member 11'.

I Preferably diameters of the perforations 17 and the corresponding transverse dimensions of the slots 16 are sullieieritly greater of the bolts5.

The slots 16 are of sufiicient'length' to ace commo date r 'a sonablevariation-s in the length ofItheboiier-section assemblies." Thus 'if an assembly is completed andthe jacket? placed thereover,'the cover' membersfmay be fitted ti'ghtly'upon thejacket 'T and'tliereafterthe bolts 15jtightene'dto ma intain the cover parts together tightly fitting upon the jacket.
